What are the advantages of computer memory in computer system peripheral and architecture of organizations?
The memories of computers are able to provide free space for their data and information.
These memories are very fast and used to transfer 1 million instructions per second for the CPU to process these instructions.
Some memories hold programs that used to help for execution of a particular program in a computer operating system for performing a task according to the requirements of the users. These users may be a programmer or end user of the operating system.
Some memories are used to store databases for a long time for end users or client users. This database is for future use for users. The database is created by the end user or may be an admin user.
These long term types of memories also help for development of new projects and application development in IT fields.
What is ROM in a computer system?
ROM stands for Read Only Memory.
ROM is a permanent memory which is used to read only by the CPU.
When the CPU is doing processing work, the Read Only Memory is used to execute some functions which are permanently stored in the ROM.
ROM stores function permanently during the manufacturing process.
The ROM stores functions such as cos theta, sine, trigonometric expression and much more that is in mathematics functions.
When the CPU needs to solve the problem by using the cos, cosine method, it uses these functions from the ROM which is permanently stored in the Read Only Memory.
The functions stored in the ROM cannot be deleted permanently from the Basic ROM, not for other types of ROM such as EPROM, EEPROM etc.
Some types of ROM are erasable by the different methods in the manufacturing places such as the industry of making memories.
The flash drive can transfer the data from the computer system to another computer
Flash drive is a portable storage devices which are used to store for a long time to access and retrieve the database which has stored permanently.
It can operate and manipulated by the operating system when the user access the flash drive into the computer system and access the database store into the flash drive space.
So the flash drive device is easier to carry on the pocket and hand with connection of the USB port of the computer system.
Flash drives can store upto 1 tb according to the capacity of storing the data into the space of the flash drive device.

| This image shows the port of usb in the front of the cpu cabinet of the desktop computer system and after connecting the usb flash drive is used to provide the notification on the operating system for detecting a new hardware. |
Some old version have different in their size which is difficult to connect with new version of usb port for the flash drive of USB on the computer system and the operating system access with the new version of the usb device male port on the computer system and USB provide easy to connect with easy to detach the usb by permission to eject the usb from the operating system feature then eject by manually from the cabinet of CPU on the computer system.
Which memory device is used to transfer the data?
- A) Flash drive or pendrive
Answer is A) "flash drive or pen drive".
The flash memory is used to plugin or inject or connect into the cpu cabinet through the usb port because the flash drive has a usb male port to connect the usb female port.
You can use so many times or erase also many times such as format or delete the files free up the space again and again to copy and paste the new database into the free space available on the flash drive or pen drive. Here the memory card also does this type of flash drive characteristics same as pen drive.
Which memory is used for temporary uses on the computer system when the computer starts and after completely boot processes?
Answer is A) "RAM".
Because the RAM is a temporary memory which is used for running the application software when the user clicks to open the application file icon and run the application software on the operating system on the computer system.
The RAM is used for storing some files which are used for the support and processing of some files and running uses by the user on the application software on the computer system.
The RAM is used when the application is currently used in the operating system on the computer.
The RAM removes the data when the application software has been closed by giving the command to close the application software through the clicking of the cross red sign on the right side upper corner of the form of application software.
Which memory is used as a permanent memory storage device of the computer system?
Answer is D) "both A & C".
The hard disk is used to provide the permanent memory space to the computer system to store the operating system and application software and also the user database.
The Erasable ROM, The ROM also can be erased but it is used as a permanent memory because of the formula such as tan, cot, sine, etc. Types of data which are used by the CPU when the CPU needs to process the program and compute the value of the program uses those types of formula to solve and provide the output data.
Which memory device is used to install the Operating System in the computer system?
Answer is A) "Hard Disk Drive".
The hard disk drive is an old device according to the new generation of the computer system and operating system but it is used to install all the types of files of the operating system.
The operating system and the user database related to the operating system are also saved in the hard disk drive.
The hard disk drive is a permanent memory of the computer system which gives stability of data to again access the saved database from the permanent memory hard disk drive of the computer system.
Which memory is used to store instructions and programs which are ready for execution after processing through the CPU?
Answer is A) "Cache memory".
The Cache memory is used to store instructions and programs which are ready for processing and waiting into the cache memory for a short time.
 |
| In the figure shows the cache memory storing the program and instructions. |
The cache is temporarily used in the motherboard and computer for storing programs also in their space of cache memory.
The cache memory is printed on the PCB means printed circuit board or you can say the cache memory is manufactured on the motherboard which is known as printed circuit board or PCB of computer systems.
And the cache memory is not a detachable device, it is only manufactured on the motherboard permanently.
Which device is a mechanical storage device installed on the computer system in an earlier time into the cpu cabinet?
Answer is B) "Hard Disk Drive".
The hard disk drive is a HDD device which is a mechanical storage device because it controls a spindle to move the disk inside the device and attached with the PCB and control with ide connectors available on the motherboard PCB.
The HDD is a round per minute speed calculated to read and write the data into the disc rotating inside the covering of the hard disk drive.
But today the HDD is rarely used in the computer because the higher version of the operating system is available in the market and it cannot be handled properly. After a year the end user faces the problem of the newer versions of the operating system crashing the data on their personal computer or official computer system due to the hard disk drive (HDD).
Which type of memory is used to store the data of sin, cos, tan etc. And the cpu takes it for processing work?
Answer is B) "ROM".
The ROM is used for storing the data of sin, cos, tan etc. Depends on the types of rom to read only the data which has been stored during the manufacturing of rom on the motherboard of the computer system.
The ROM stores those types of sin, cos, tan for processing by the cpu, the cpu accesses the rom when it needs those types of data and formulas to apply to solve the program and compute it to provide the output data to the output unit of the computer system.
Which device is used to download the file into the space of memory following below here:
Answer is B) "HDD or SSD".
